I currently use a pair a dual 15" JBL Full range speakers that I built for my sound reinforcement system. I just bought a pair of JBL 2226's(4 Ohm version) to extend the frequency response of the system down to at least 35Hz. I want to make the most of the power I have to push them (750watts x 2 into 4 ohms stereo). I was thinking of a vented box of about 6 cubic feet tuned to 30Hz. But I guess I would need at least 1200 watts to get those monsters booming!!!! how about a folded horn?? Those tend to be efficient. Would that work for me?? Since designing horns are quite difficult, does any one know of a horn or vented box that will have those woofers thumping????

-Thanks alot
